MACHINE FOR PERFORATING BANDS OF TYPE-SETTING- MACHINES.

To' all whom it may concern:

Be it known that I, HEINRICH DREWELL, subject of the German Emperor, residing at charlottenburg, Germany, have invented new and useful Improvements in Machines for Perforating Bands of Type-Setting Machines, of which the following is a specification.

The present invention relates to type-setting machines, and an important object is to provide improved means for making perforated bands for operating the same automatically.

Perforated bands, which are used for operating type-setting machines, are made in known manner by means of perforating machines, in which the depression of keys causes corresponding symbols to be punched in the band. These symbols cause types or matrices to be set up and also control all other functions which the perforated band has to bring about in the automatic typesetting machines. The operator at the perforating machine can therefore initiate all the operations necessary for making matter by means of the perforated band, such as, for example, the division and justification of the lines, setting up space-bars or justifying members, and the like. The line is terminated by pressing a key for the end of a line, or in like manner, while observing a suitable device which indicates the lengths of the line. The spaces between words are also represented on the register band by striking special key. When terminating a line its justification must be taken into consideration at the same time. This may be done in manifold ways, according asto whether the justification is prepared beforehand at the perforating machine by calculating the shortage which is to be j ustified or in similar manner or whether it takes place on the type-setting machine alone without the cooperation of the register band.

In the present case the following supposition as to j ustification is made, which how ever is not connected with the essence of the invention here described, but is only one example of a constructional form. Justification is effected by enlarging the breadth of the elements or members separating Words in the type-setting machine, automatically,

without the cooperation of the composer or of the perforated band. For enlarging these elements or members an upper limit is given, beyond which they cannot be enlarged. But in order to obtain greater spaces between words than are given in this manner, the composer can cause a second member to be set up besides the standard member separating words, the breadth of which second member is added to that of the preceding element.- The breadth of this additional member does not require to be variable. Whether it is necessary in a given line to add such additional elements to the standard elements between two words can be known by the composer only after he has written and perforated the line on the register band. Then by pressing a special key he can per forate in the register band a symbol which, when the band is operating the type-setting machine for the whole line behind which the symbol is situated, causes an additional element to be added to the element between two words. In the type-setting machine this symbol must operate, however, in front of the line for which it is valid. Moreover, there must be taken into account two additional symbols which can be perforated in the perforating machine after the groups of holes which their action is to affect, but which must operate in the type-setting machine before these groups of holes. These are, for example, the symbols by means of which the actions of certain groups of holes are to be eliminated. If the composer notices that he has written incorrectly in the last written word, by pressing on a special key he can eliminate the action of that group of holes which represents this word. The pressure on the key produces a perforated symbol in the register band behind the defective group of holes. Further, the composer can cancel an entire line or make in operative the concerned group of holes of the register band if he wishes to do so for any reason, and this also is effected by simply pressing a key and thereby producing a corresponding perforated symbol behind the group of holes corresponding to the line. A re ister band prepared in this manner contains the perforated symbols for making inoperative certain groups of holes and for justifying lines behind those groups of holes for which the perforated symbols are valid.

For practical reasons it is preferable and sometimes necessary to introduce the register band into the type-setting machines in such manner that the symbol first perfo- 'ated begins the work in the type-setting machine, so that the order of composing is consequently the same as that of the holes. If a band made according to the above described method were passed on at once to the typesetting machine, the perforated symbols for making groups of holes inoperative and for justifying lines would act at the wrong place, namely after the apper taining groups of holes. Now the principal object of the present invention is to provide means by which this action can also be brought about at the correct place even when the register band runs forward. For this purpose, before the register band passes into the type setting machine it is sent through an auxiliary apparatus which will complete the perforation on the band. That is, the auxiliary apparatus makes in the band supplementary holes, which are placed before the concerned groups of holes. The punches making the supplemental holes are selected by means of those perforations which the operator has made behind the concerned groups of holes. For example, if a line is to be justified the operator causes the justification holes to be punched behind the representation of the last character of the line. lVhen the band has been completed, it is sent through the auxiliary apparatus and this will cause the perforation of new holes representing justification before the first character selecting holes of that line. Now if the band runs forward into the type setting machine, the holes punched by the auxiliary apparatus will operate the justification device and bring it into correct position for justifying the following line.

In the auxiliary apparatus the register band runs backward and for this reason those symbols of justification or cancellation which are placed behind the representations of line or words to be justified or canceled by them, will act before these representations pass the auxiliary apparatus. The action of those justification or cancellation symbols prepares in the auxiliary apparatus the perforation of new holes by selecting certain punches. If the holes which determine the beginning of the line or word to be justified or canceled, pass the auxiliary apparatus the feeding of the band is stopped automatically and the punches before selected are operated, thus making a new symbol of justification or cancellation at the beginning of the respective group of holes. The mechanisms for stopping the band and operating the selected punches are released by means of the word separating symbol if a word is to be cancel-ed, and by means of the line separating symbol if a line is to be justified or canceled.

Besides the perforated symbols referred to above, other optional perforated symbols can also be transposed by the auxiliary apparatus, for example perforated symbols which correspond to an amount of ustification calculated mechanically in the perforating machine.

The above described method which forms the foundation of the invention requires an auxiliary apparatus which can be constructed in different ways. The constructional f0 m described hereafter by way of example is thought of as for a register band having 11 different positions of holes in one transverse row. Since only the possible combinations by twos are employed, different perforated symbols can be formed. Vhen a suitable reversing device is used about 100 different characters can be set up and other functions of the machine brought into operation by means of these symbols.

The apparatus is represented in the accompanying drawings in which:

Figure l is a sectional elevation showing the apparatus, the front wall and some parts having been removed; Fig. 2 is a plan of the apparatus, some parts being omitted; Fig. 3 is an elevation of some parts of the driving device seen in the direction of the arrow A in Fig. 2; Fig. 4 is a bottom plan view showing the system of magnets seen in the direction of the arrow B in Fig. 1; Fig. 5 is an elevation showing the system of punch selecting levers as seen in the direction of the arrow C in Fig. 1; Figs. 6 and 7 are vertical sectional and front elevations respectively of the striking frame of the punching device, the latter view as seen in the direction of the arrow C in Fig. 1, whereas Fig. 8 shows a portion of the perforated band before the perforated symbols have been transposed, and Fig. 9 shows a portion of the perforated band after the perforated symbols have been transposed.

Referring to the drawings, the register band contains, as already mentiol'ied, 11 rows of holes which are denominated in the figures with a, b, 0, (Z, c, f, g, h, 2', is, Z. Each two holes in one transverse row of the band form a perforated symbol which corresponds to setting up a type or other function of the type-setting machine.

Those functions which come into the question for the invention herein described are ending a line, spacing between two words or setting up the justifying element, making inoperative or eliminating entire lines and individual words, and enlarging the spaces between words or so-called post-spacing.

These functions are represented by the following perforated symbols: End of line a Z), space between two words (Z 9, the symbol for eliminating lines Z) Z, the symbol for canceling a word a Z, the symbol for post-spacing (Z 6- It is to be noted in addition that the symbol a Z is behind the words which are to be eliminated, and consequently acts after them in the type-setting machine. It is therefore used in order to cut in the action of the register band in the type-setting machine after it has been stopped working by a perforated symbol in front of the words which are to be eliminated. This latter symbol consists of the holes f g and is produced in the auxiliary apparatus by the hole f being perforated in addition in the transverse row of the band in which the symbol (Z 9 is for the space between two words. The hole (Z in the same transverse row is then superfluous, but does not exercise any disturbing efiect.

The auxiliary apparatus contains the following principal parts; the feeding device for the paper band; the reading device which causes the perforated symbols to act on the other parts of the apparatus; thepunch selecting device for selecting the proper punch; the punching device for punching the holes; and the driving device which alternately drives the band and punches the holes.

Driving (Zem'0e.-The parts of the apparatus are mounted between three fixed walls and in such manner that between the walls 1 and 2 those parts are situated which act on the register band, whereas the remaining parts, particularly the driving device, are mounted between the walls 2 and 3 of the frame, as clearly shown in Fig. 2. The apparatus is driven in optional manner, for example by a grooved pulley 4: which is mounted loose on the main axle 5,- (Figs. 1 and 2). Vith the pulley 4: there is con nected a bevel wheel 6 which forms one part of a differential gear formed as a coupling. The differential gear consists of the bevel wheels 6 and 7 and the planet wheels 8 and 9, as clearly shown in Fig. 2. The differential gear serves on the one hand for driving the feeding device for the paper band, and on the other hand for driving the punching device. These devices are operated alternately by means of the following arrangements: With the bevel wheel 7 there is connected a bush or sleeve 10 on which a spur wheel 11 and a ratchet wheel 12 are attached. Another sleeve or bush 13 is attached on the axle 5 and carries the pivots of the planet wheels 8 and 9. Opposite the ratchet wheel 12 there is another ratchet wheel 15 which is attached on the axle 5 and can only rotate with this axle. The ratchet teeth of the wheels 12 and 15 are directed oppositely and are rotated in opposite directions. Opposite the ratchet wheels there is a double pawl 16, 17 (Figs. 2 and 3), the arms 16 and 17 of which engage alternately in the Wheels 12 and 15. The arm 16 engages in the wheel 12 and the arm 17 in the wheel 15 and they are so arranged that they cannot both engage simultaneously in the two wheels. How the arms 16 and 17 are brought into engagement with the wheels 12 and 15 will be described hereafter. The action resulting from their engagement is as follows: If the pawl 17 is in the wheel 15, the main axle 5, which is rigidly connected with the wheel 15, is prevented from rotating. 13 is also fixed, so that the bevel wheels 8 and 9 can only rotate around their pivots. In this position the rotation of the pulley lis transmitted by the bevel wheel 6 and the bevel wheels 8 and 9 to the bevel wheel 7 which consequently rotates at the same speed as the pulley 4. The spur wheel 11 and the ratchet wheel 12 rotate with the bevel wheel 7. The spur wheel 11 meshes with a spur wheel 18 which rotates around the axle 19. On the latter there is also arranged a pinion 20 which serves for imparting rotation to the spur wheel 21. The latter is attached to the axle 22 which also carries the roller 28 for imparting movement to the paper band. From the above it will be readily understood that the roller for feeding the paper is driven as long as the pawl 17 engages with the ratchet wheel 15.

Paper feeding de'vice.-The paper feeding-roller has mounted opposite to it a roller 24 which presses the paper band 25 against the roller 23. The axle 26 of the roller 24 is mounted in a pivoted frame 27 which can be moved up anddown. The rollers 24 and 23 are covered with an elastic material, such as i-ndia rubber or the like, and feed the paper band 25 as long as the roller 23 rotates.

Reading dem'ce.The reading device consists of a row of spring-pressed levers or feelers which are normally pressed against the register band and tend to fall into the holes of the register band as soon as these holes are opposite the points of the levers. For those holes which are to be stamped subsequently in the register band and those holes which start the punching of these sub sequent holes, there are seven positions of holes which come into consideration in the present constructional form, namely those denominated with a, Z), (Z, 6, f, g, and Z (Figs. 8 and 9). Of these, the hole in the position f only is punched, whereas a special feeling lever is not required for this hole. For the holes a, Z), d, e, g-and Z there are provided feeling levers 60 60 60. 60 60 and 60 which are revoluble around an axle 61. The one end of each lever forms a point 63 which The bush &

is pressed by a spring (32 against the register band 25. At the other end of the lever there is a contact (34: which is opposite a contact screw (15. The points (33 of the feelers are situated immediately in proximity to the matrix S-L, at the lower face of which the register band 25 passes. Immediately in front of the matrix there is a bridge (36, the bottom horizontal part of which is formed like a comb. The bridge 66 is attached to the pivoted frame 27. The gaps between the teeth of the comb-like part of the bridge 66 are opposite the points 68 of the feelers, whereas the teeth of the bridge support the paper band between the feelers for preventing the baud bending and an unintentional contact being made between the feelers G0 and the contact screw (35. The register band 25 is drawn steadily through between the points of the feelers and the bridge (56, the points of the feelers being depressed as long as a hole of the register band is not opposite to them. \Vhen the latter event occurs the point of a feeler enters into this hole, a contact is made between the end 64: of the lever and the screw (35, and as soon as the hole has passed the point, the point of the lever is depressed again by the register band. The contacts brought about by the perforated symbols of the band cause electric currents to flow which operate the punch selecting device.

Punch selecting dcm'cc.The correct punch is selected, as already mentioned, with the aid of intermediate pieces 45 as 45,, 45 and 15 which are brought at the given moment between the punches e6, 443 46 463 and L6 and the plate 44. The intermediate members 4L5 to 45 each form the one end of rods 70 70. 70,, 70 and 70 which are connected at their other ends with the levers 71 71,, 71 and 71 (Fig. 5). These levers are under the action of springs 75 and 76 which tend to so rotate them that the intermediate members eta, to 415 arrive be tween the punches 46 to &6 and the plate 44. (Fig. 1.) The lever 71 is mounted firmly on the axle 78 and is thereby connected with the lever 72 fixed on the same axle. The levers 71 and 71 together with the lever 74 are attached on the axle 77. The levers 71 and 73 are attached on a bush 79 which is revoluble loosely on the axle 77, as clearly shown in Fig. 5. The levers 72, 73 and 7st are provided at their ends with enlarged portions 99, 100 and 101, and are held in their normal position by hooks or catches 93, 94:, 96, 97 and 98 (Fig. 4) against the pull of the springs 75 and 76. The catches 93 to 98 form the one end of two-armed armature levers 88 to 92, the other ends of which carry the armatnres 81 of the electromagnets 83 to 87, as clearly has at its end two catches 96 and 97. The remaining armature levers have each only one catch or hook. Each two adjacent catches 93 to 98 engage one of the levers 72, 7 3 and 7 1. For this purpose the latter are provided at their free ends with the enlarged portions 99 100 and 101 mentioned above. In their normal position the ends 99, 100 and 101 of the levers are held by the hooks or catches 94, 95 and 98 which correspond to the electromagnets 88, 86 and 87. Of these, the magnet 83 operates as soon as the combination of perforations a Z of the register band acts on the points of feelers. When the catch 94 has released the end 99 of the lever the latter lies against the catch 93 which stands back somewhat. In consequence of the small movement of the end 99 of the lever which is caused, the catch 94 is not able to hold the end 99 of the lever afresh when the electromagnet 83 releases its armature. Now if the electromagnet 84 operates, the end 99 of the lever is completely released. In consequence of the pull of the spring 75 the lever 7 2 then rotates the axle 78, and the'lever 71 brings the rod 70: between the punch 46 and the plate 44. The two electromagnets 83 and 84: operate when a word is to be canceled, that is to say when the symbols punched for this word in the register band are to be made inoperative. The composer at the perforating machine punches the combination of holes a Z behind such a word. Since the band runs backward through the correcting apparatus, this symbol comes under the feeler 63 in front of the word which is to be canceled and causes the electromagnet 83 to become energized and the hook 9st to be withdrawn from the end 99 of the lever. The further action, namely punching the real eliminating symbol, only occurs when the space-symbol in front of the beginning of the word to be canceled is opposite the feelers 63. and 63 At this moment the electromagnet 8st be comes energized and completely releases the lever 72.

The electromagnets 85, 8G and 87 operate when those functions come into play which serve for canceling or post-spacing an entire line. The electromagnets 8G and 87 begin the stamping of the concerned perforated symbols when the end of the line which is to be canceled or justified in this manner passes the feelers 63 to (33 If one of the combinations of holes (Z c or 6 Z is situated at this end of the line, one of the magnets 86 or 87 operates. Now if the symbol a b for the end of a line, which is in front of the beginning of this line, has passed the feelers, the electromagnet 85 also operates, and one of the ends 100 or 101 of the levers is completely released. For example, if the electromagnet 86 is energized at the end of a shown in Fig. 4. The armature lever 91 I line, at the commencement of this line the end 100 of the lever will be released, and the levers 73 and 71. will follow the pull of a spring 76, and the latter will bring the i11- termediate members 45 and 45. between the plate 44 and the punches 46 and 46. by means of the rods 70 and 70 In like manner the excitation of the electromagnet 87 causes the lever 74, with the aid of the two levers 71 and 71 connected with it, to bring the intermediate members 45 and 45 between the corresponding punch and the plate 44.

Punching device-The punching device is driven by means of the bevel wheels 8 and 9 (Fig. 2) as soon as the ratchet wheel 15 is released from the pawl 17 and the ratchet wheel 12 is held by the pawl 16. In this case the bevel wheel 7 is prevented from rotating and the bevel wheels 8 and 9 are compelled not only to rotate around their pivots, but to drive these pivots around the axle 5 which is also driven. On the axle 5 there are also attached the ratchet wheel 15, cam 30 and cam 31. The cam 30 serves for bringing about the stoppage of the axle 5 at the right time in a manner more particularly explained hereafter. When the axle 5 rotates the cam 31 occassions the additional holes to be punched in the register hand. For this purpose it acts on a twoarmed lever 82 as clearly shown in Fig. 1; the latter is revoluble around the axle 38 and carries two sliding rollers 84, 35 which are alternately thrown back by the projection 36 when the cam 31 rotates. .The arm 37 of the lever is rocked and first raises the frame 38 by means of the rod 39, the frame being then pulled down. The frame is raised by the action of the cam on the roller 35 and is pulled downward by the action on the roller 34. The frame 88 consists of two side parts 40 and two rods 39 and 41, as clearly shown in Fig. 7. The latter rod is mounted in the ends of two levers 42 which rock around the axle 43. The levers 32 and 42 guide the frame 38. The latter is provided in its upper end with a plate 44, by means of which the motion of the frame is imparted to the punches 46. to 46 with the aid of intermediate members 45 to 45 The punches are guided in two guide-plates 49 and 50 and each punch possesses an abut-' ment or lug 51. Against these lugs there abuts a plate 52 which is connected by the side parts 53 (Figs. 6 and 7) with the frame 38 and returns the punches into their normal position (Fig. 1) after the band has been punched. Above the guide-plate 50 is situated the matrix 54 into which the punches penetrate through the paper.

The operation of the punching device is controlled by the punch selecting device. For this purpose the driving device is reversed by the movement of the levers 72,

the other lever.

7 3 and 74, so that the driving device drives the punching device instead of the paper feeding-mechanism. Two levers 105 and 106 are arranged in front of the levers 72, 73 and 74 as clearly shown in Figs. 1 and 5. The lever 105 is opposite the lever 7 2, whereas the lever 106 carries a cross-bar 107 which is opposite the two levers 73 and 74. The levers 105 and 106 are attached to bushes or sleeves 108 and 109 which rotate loosely on an axle 110. On the latter axle there is attached a bush or sleeve 111, as clearly shown in Fig. 5. It is situated between the bushes 108 and 109 and has two teeth 112 and 113 which are opposite two other teeth 114 and 115 on the bushes 108 and 109. The teeth are so placed that when one of the levers 105 and 106 is thrown back, the axle 110 is compelled to rotate with the lever without its motion being imparted to On the one end of the axle 110 there is attached a lever arm 116, as clearly shown in Figs. 1, 3 and 5, which is connected at the reversing coupling with the double pawl 16, 17 by a rod 117. The connection is arranged such that when one of the levers 105 and 106 is thrown back by one of the levers 72, 73 and 74, the pawls 16, 17 are reversed and the punching device is driven instead of the paper feeding-mechanism. In order to stop the punching device and to feed the band still farther, on the main shaft 5 there is arranged in addition the cam 30, as clearly shown in Figs. 2 and 3. Further, on the double pawl 16, 17 there is attached an arm 118, the roller 119 of which lies against the cam 30. The latter has a notch 120 into which the roller 119 enters as soon as the main shaft 5 reaches its normal position. In this position the pawl 17 is in the teeth of the wheel 15, so that the punching device remains at rest whereas the device for feeding the band continues to move. The roller 119, the arm 118, as well as the pawl 16, 17 connected with it, are under the action of a spring 121 attached to the lever arm 116, which spring tends to bring the pawl 16, 17 into that position in which the feedlng device operates and the punching device is stationary. The spring 121 is overcome when the springs 75, 76, (Fig. 1) whlch throw back the arm 116 by means of the clearly shown in Figs. 1, 6 and 7. These dogs are parts of bell-crank levers which are journaled on a rod 128 attached in the frame 38. At each of the dogs 126 and 127 there is an arm 129 carrying a leaf-spring 130 which rocks between a stop 131 and a set-screw 132, as clearly shown in Fig. 1. hen the punching device is thrown into gear one of the arms 125 arrives into the position shown in dotted lines in Fig. 1. Now when the frame 38 is raised by the cam 31 the leaf-springs 130 lie against the pin 131, and when the frame 38 is raised still farther the dogs 126 and 127 rotate around the rod 128, and one of the dogs engages on the point of the arm 125 opposite to it. Now when the frame 38 returns into its lower position, the dog 126 or 127 drives the concerned arm 125. That one of the dogs 126 and 127 which has not seized the arm 125 returns into its normal position, in consequence ofits leaf-spring 130 striking the set-screw 132 opposite to it, without contacting with the arm 125 opposite to it. The other dog which seizes one of the arms 125 returns this into its normal position, since it is held at the arm 125 by friction against the action ofits leafspring 130 until the arm 125 arrives into its normal position.

On account of the arms 125 being returned the levers 105 and 106 connected with them are also returned into their normal positions and likewise the levers 72, 73, 74 which engage behind the catches 94, 95 and 98. In this manner the action of the springs 7 and 76 on the axle 110 and the arm 116 is canceled. The latter is now under the action of the spring 121 again which likewise brings it into its normal position when the roller 119 lies in the notch 120 of the cam 30. In this manner the pawl 16, 17 is then reversed, so that the punching device steps and the perforated band is driven. The feelers 60 to 60 can be connected with the electromagnets 83 to 87 according to known methods of connection, for example according to the Letters Patent No. 864,519. F 8 shows a portion of a register band as it comes out of the perforating machine. On this portion the symbol for the end of a line at 135 consisting of the combination of holes a 6 forms the conclusion of the pre ceding line. Of the other perforated symbols, the three pairs of holes which represent the word den are to be made inoperative by the symbol a Z' at 136. Lastly, the line is broken oif behind the word Strom and here the symbol 6 Z for canceling the entire line is placed at 137. At 138 there is the symbol a b for the end of a line which separates this line from the next. The register band moves in the perforating machine and in the type-setting machine in the direction of the arrow 139 from which it will be readily understood that the perforated symbols 1 at 136 and 137 would only be operative after those groups of holes which are to be made inoperative by them. In order to bring about the action at the right time, the band is passed through the herein described auxiliary apparatus and *the combinations of holes 140 and 141 are punched. Fig. 9 shows the band thus treated. This band runs in the auxiliary apparatus in the direction of the arrow 142, so that it will be readily understood that the symbol 137 passes the auxiliary apparatus before the part of the line to which it relates. The perforated symbol 140 is punched corresponding to the symbol 137 as soon as the symbol 135 for the end of a line is opposite the points 63 of the feelers of the auxiliary apparatus. The matter is similar with regard to the symbols 136 and 141. The former acts in the auxiliary apparatus in front of the concerned group of holes and causes the hole f to be perforated at 141 at the moment when the symbol (Z dividing a word at 141 reaches the points 63 of the feelers. Now there are three holes d, f, g in the same transverse row of the band, of which the two holes f and 9 cause the three combinations for the word den to be made inoperative. From the portion of the register band represented and from the description of the auxiliary apparatus it will be readily understood that a commenced or full line can also be eliminated or canceled when one or more words within this line have already been canceled. 1n the type-setting machine a canceled word has also to occasion the symbol a Z (at 136) and after a canceled line the symbol 6 Z or a b (at 137 and 138) to occasion the setting operation to be cut in again. In what manner this can be done is already known.

The above described method and apparatus can also be used for register bands of other kinds, for example for perforated bands for operating telegraphic apparatus or musical instruments. In the case of the latter the original band may be treated in the above described manner before it is manifolded.
